I have a slight (2-3 cent) swelling down my right leg. It started with my calf being swollen, I had a Venus study(?) for a blood clot and they didn't find anything. I also had a MRI on my left calf, no clot, no fluid, no growth and the muscle looks normal. Now i have a hard knot on my knee cap and my foot seams larger also. I sometimes have pain in my right hip, but am told it's not connected to the swelling. Also one of the veins on the inside of my right foot is popped out all the time now. Both my doctor and the Ortho don't know what's causing it.I have had no trauma to the area.
